Abstract: A block prediction method for decoding a picture, according to the present invention, comprises the steps of: deriving a reference block from a reference picture to predict a current block in a current picture; determining a reference illumination compensation (IC) parameter; generating an illumination-compensated reference block by applying reference IC to the reference block on the basis of the reference IC parameter; and generating a predicted sample of the current block on the basis of the illumination-compensated reference block. According to the present invention, an illumination difference between the current block of the current picture and the reference block of the reference picture can be compensated for, block prediction efficiency can be increased, and a data amount of a residual signal to be transmitted from an encoder to a decoder is reduced. Therefore, compression and coding efficiency can be increased.

Abstract: A beam-scanning optical design is described for achieving up to kHz frame-rate optical imaging on multiple simultaneous data acquisition channels. In one embodiment, two fast-scan resonant mirrors direct the optical beam on a circuitous trajectory through the field of view, with the trajectory repeat-time given by the least common multiplier of the mirror periods. Dicing the raw time-domain data into sub-trajectories combined with model-based image reconstruction (MBIR) 3D in-painting algorithms allows for effective frame-rates much higher than the repeat time of the Lissajous trajectory. Because sub-trajectory and full-trajectory imaging are different methods of analyzing the same data, both high-frame rate images with relatively low resolution and low frame rate images with high resolution are simultaneously acquired.
